ing had to the accompanying drawings, in

which like numerals refer to like parts.

This invention relates to car doors, and in particular to railwayoardoors.

The chief object of this invention is to provide a railway car or thelike with a sectionalized door, such that the loading and unloadingofsaid car will be facilitated by use of said door.

The chief feature of the invention consists in sectionalizing the doorand providing the several sections with suitable supporting means,whereby the same may be moved from the door closing position into anon-closing position and whereby said door may be locked in either ofsaid positions, or may be secured in an intermediate position.

Other features of the invention relate to the details thereof.

The full nature of the invention will be understood from theaccompanying drawings and the following description and.

. from the same and is curved inwardly from claims.

In the drawings, Fig. 1 is a transverse sectional view of a railway carto which the invention has been applied, the door being illustrated intwo positions. Fig. 2 is a side elevational view of a railway carshowing the parts in thedoor'closing position and being locked orsecured therein. Fig, 3 is a sectional view of the locking means takenon line 3-3 of Fig. 2 and in the direction of the arrows the dottedlines showing the door secured in the open position. Fig. 4 is asectional view of the track support taken'on line 44 of Fig. 1 and inthe direction of the arrows. Fig. 5 is a sectional view of the doorconstruction showing one of said sections in the door closing position,said sectional view being taken on line 5-5 of Fig. 1.

In the drawings there is illustrated the usual box or railway car, theroof of which is supported by suitable beams 20 and the sides thereofbeing provided with the usual door openings 12, said door openings beingformed of the side posts 13, which posts, as shown clearly in Fig. 5,are substantially L-shaped in cross section, and to the same are secureda- T-shaped track 14.

Said track is secured to the post such that the head of the T bearsagainst one of the interior faces of the L-shaped post, so that the bodyof the T or bearing portion 15 thereof forms a channel between itselfand the door post 13. As shown clearly in Fig. 6B

there is secured at each end thereof a spring plate 18, each springplate is bent and extends angularly from said section and then extendsparallel thereto. Upon the parallel portion of said angular extension issuitably supported a roller 19, which roller, as shown clearly in Fig.5, is rollable between said door plate 15 and the door post 13. Withthis construction, itwill be understood that pressure from the contentswithin the car will bear against the sections 16 and force said sectionsto bear against the bearing plate portion 15, thereby forming a tightjolnt. between the door post and said sections.

' As shown clearly in Fig. 1, the trackway 14 at each side of the doorextends upwardly said door and then extends substantially parallel tothe car floor and at right angles to the door closing position. In Fig.1 the usual opposite doors of the car are each provided with a pair ofbent trackways, and as shown in said figure, the overhead portion of oneof said trackways is positioned abovethe overhead portion of the otherof said trackways. Thus, both door openings are provided with door meansfor closing the same.

While the door closing portion of the trackway 13 is secured to the doorpost, the

overhead portion of said trackway is supported from the roof of the car.Associated therewith is a yielding shock absorber construction which isillustrated in detail in Figs. 1 and 4, in which 20 indioates a pair ofbeams, one of which supports depending and angularly extending bracketsor braces 21. Each bracket or brace extends towards a strap or hanger 22secured to the adjacent beam. The strap 11 or hanger 22 suitablysupports a strap or plate member 23, which plate IHQIIlbGI' supports abolt 2 1, said bolt extending through the free end of the angularlyextending brace 21. Positioned upon said bolt member and upon each sideof the brace 21 is a coiled spring 25 concentric with said bolt memberand secured thereon by means of the .washer and nut 26 and 27, wherebythe tension of said spring members may be suitably adjusted. One end ofeach of the springs 25 abuts the brace 21 and the other ends oi? thesprings abut the plate 23 and washer 26 respectively. The tour supporting straps or plates .23 carry the four T- shaped trackways 14 in twopairs and in superposed relation by means of suitable bolt members 28.The hereinbefore de scribed construction provides that twisting orweaving of the car or undue vibration thereof will not be transmittedtothe trackways in a sufiicient amount to permanently deform or damage thesame.

:It will, of course, be understood that there is sufiicient overheadtrackway to receive and support alltof the door sections when it isdesired to have the door opening entirely clear. There is, therefore,provided at each end of the traclzwaya suitable stop member, such as thebolt 29, for limitmg .the movement of the door sections in thisposition. The means for locking the 'door sect1ons 1n the overheadposition consists in a hinged hasp member 30 secured at one .end to thedoor frame and provided in its end with a staple receiving opening 31.The lowermost door section, when in the door closing position, isprovided with a suitable loop or ring member 32-hingedly supported at 33in a recess 3 1. The ring 32 is adapted to be associated with the hingedhasp 30 such that a portion of said ring extends through the opening 31when the lowermost door section-is in the elevated position. as shown bythe dotted lines in Fig. 3 and is secured. in said extending position bymeans of a snap hook 35 secured to the door opening by suitable means,such as the link chain 36 which is shown in Fig. 2 as associated withthe topmostdoor section to lock the door in closed position. Thus, the

workmen may hook from the staple r ng so as to release the hasp therefrom and permit said door section to be -:lowered into the door closingposition.

The means for locking the door sections in the door closing positionwhen gall of said sections are in said position, consists inv suitablemeans, such as the ring 132 which is provided the outer lface of theupper door section. The hinged hasp member 30, when associated with theupper door section, may be secured thereto by means of a suitable lock37, or by means of the usual car seal 38.

As shown clearly in Fig. 5, additional locking means is provided, ifdesired, and this locking means consists of a catch member an suitablysecured to the door post 18, see Fig. 5,said catch member being adaptedto receive the finger operated latching bolt 1-1, said bolt beingprovided with a finger piece 12, and said bolt being slidably supportednear one end of and upon a door section 16. i

If desired, it will, of course, be understood that a plurality of thebefore mentioned lockmg means may be provided, both upon the door postsand uponthe door sections. Furthermore, said sections maybe separatedrather than hinged together, or all m ay be hinged together. When saidsections are separated, orat least a portion thereof are separated, thenthe same are provided with a plurality of bolt latches and said .doorframes are provided with a plurality of bolt catches, said sections maybe secured across the door opening in spaced relation soas to provideventilation through-the door opening such that'the car may be used foranimals, or for the preservation '01: material which requiresconsiderable ventilation to prevent spoilage or damage, i

The invention claimed is:

1. Ina railway car, the combination with a roof, apair of supportingsides, each provided with an opposite door opening, of a pair oitrachways each associated. with a door opening, said trackways extendingpar.- allel to the sides oi said door opening 'and inwardly above saiddooropening in .substantially parallel relation-with said car'roof,means for supporting the parallel inwardly extending trackways of bothdoor openings in superposed relation, and a spring construction foryieldingly engaging the trackway supporting means to prevent relativemovement of the trackways iu the weaving, twisting and vibratingmovement-ofthe car, said means comprising a spring construction.
